C Correct answer
Explanation

Relative speed = 6 - 4 = 2 km/hr. Time = 6 minutes = 6/60 hours = 0.1 hours. Distance = Relative speed * Time = 2 * 0.1 = 0.2 km.

AI explanation

When the boys run in the same direction, their relative speed is the difference of their speeds, 6 km/hr minus 4 km/hr, which equals 2 km/hr. The time they run is 6 minutes, which is 6/60 or 1/10 of an hour. Using the formula distance equals speed multiplied by time, the distance between them is 2 multiplied by 1/10, which equals 0.2 km.
